CompactRIO 32-Channel Single-Ended/16-Channel Differential, ±200 mV to ±10 V, 16-Bit Analog Input Module
You can use an FPGA I/O Node, configured for reading, with this device.
Use the FPGA I/O Node to access the following terminals for this device.
Terminal | Description |
---|---|
AIx | Analog input channel x, where x is the number of the channel. The NI 9205 has AI channels 0 to 31. The channel is sampled using the currently configured terminal mode and voltage range. You can configure these settings at edit time using the C Series Module Properties dialog box or at run time using the Set Terminal Mode or Set Voltage Range methods. |
DI0 | Digital input channel used to access the module digital line, which is labeled PFI0. This terminal is not available for an onboard NI 9205 on a Single-Board RIO (sbRIO) device. |
Trig | Returns the output of the module trigger circuitry. Use the Set Triggers method to configure the trigger circuit. |
DO0 | Digital output channel 0. This terminal is not available for an onboard NI 9205 on an sbRIO device. |
Refer to the Conversion Timing topic for information about the order and timing of conversions for these I/O channels.
This device supports only the Arbitrate if Multiple Requestors Only option for arbitration. You cannot configure arbitration settings for this device.
This device does not support any I/O methods.
Use the FPGA I/O Method Node to access the following module methods for this device.
Method | Description | ||
---|---|---|---|
IO Sample | Acquires a single sample from the module. The channel number, terminal mode, and voltage range are all configurable at run time.
Refer to the NI 9205 Basic IO VI and the NI 9205 Advanced IO VI in the labview\examples\CompactRIO\Module Specific\NI 9205\NI 9205 Basic IO\NI 9205 Basic IO.lvproj and labview\examples\CompactRIO\Module Specific\NI 9205\NI 9205 Advanced IO\NI 9205 Advanced IO.lvproj for examples related to this method. |
||
Restore Last External Calibration Constants | Restores the calibration constants of the module to the factory values. You must enable self-calibration on the C Series Module Properties dialog box to use this method.
Refer to the NI 9205 Self-Calibration VI in the labview\examples\CompactRIO\Module Specific\NI 9205\NI 9205 Self Calibration\NI 9205 Self Calibration.lvproj for an example of using this method. |
||
Set Terminal Mode | Sets the terminal mode for a channel as RSE (referenced single-ended), NRSE (non-referenced single-ended ), or DIFF (differential). This method overwrites the value you configure in the C Series Module Properties dialog box. | ||
Set Triggers | Sets the trigger output to one of the following values:
|
||
Set Voltage Range | Sets the input range for a channel as ±10 V, ±5 V, ±1 V, or ±200 mV. This method overwrites the value you configure in the C Series Module Properties dialog box. | ||
Write Self-Calibration Constants |
Replaces the calibration constants of the module with new values. You must enable self-calibration on the C Series Module Properties dialog box to use this method.
Refer to the NI 9205 Self-Calibration VI in the labview\examples\CompactRIO\Module Specific\NI 9205\NI 9205 Self Calibration\NI 9205 Self Calibration.lvproj for an example of using this method. |
This device does not support any I/O properties.
Use the FPGA I/O Property Node to access the following module properties for this device.
Property | Description |
---|---|
Linearization Coefficient x | (Optional) NI-MCal linearization coefficient x, where x is the number of the linearization coefficient. The NI 9205 has linearization coefficients 3 to 0. You can use these coefficients in calibration to compensate for some types of measurement nonlinearity inherent in this device. When returning calibrated data from the FPGA I/O Node, the Linearization Coefficients are not used to calculate the calibrated data. This means that calibrated data returned in FPGA does not compensate for the measurement nonlinearities in the device. Refer to the NI 9205 Advanced IO VI in the labview\examples\CompactRIO\Module Specific\NI 9205\NI 9205 Advanced IO\NI 9205 Advanced IO.lvproj for an example of this concept. |
